Blackbody_chart - Change Log

This application displays blackbody curves at various temperatures.

02-04-17 v 0.1	Initial release
02-06-17 v 0.2	Added B(λ)/T⁴ function I was curious to see what it looked like Made Quick select option labels more generic and changed them to buttons The previous method was confusing. Unfortunately, that makes buttons all different widths - fixed via a style sheet. Added more parameters to the Quick select options They now include the y-max and scale fields. I adjusted all the defaults to produce better graphs. Added a Spectra image size control There is now an option to allow the visible spectra go to the top of the graph Fixed three y-axis labels Three of the y-axis dimensions didn't include the x-axis info - log(λ)
09-22-17 v 0.3	Fixed secondary x-axis The wavelength secondary axis was not scaling when the x-axis zoom was changed

Add a cross browser color picker: The HTML standard color picker only works in Chrome, partially works in Firefox
Option to divide the "solar" (5600K) spectra by the distance to the Sun: The B(λ)/T⁴ will be more useful with this capability
Add a list of interesting temperatures: Sun, light bulb, person, hot day, cold day, steel temperatures - red, white, other
Ability to change an axis to log: That and many other "standard" chart options - this will take a while
A page explaining the options and how to use them: Seems obvious
Add tabs so more controls can be added: Seems obvious
Plot power verses wavelength and frequency at the same time: This clearly shows that the peak and distribution are dependent on the chosen representation
Find (display) total power and compare to SB result: My other program already does this - it would be a nice addition here
Wrens law: Show that the peak power follows the theory
